You can take out the electronics with some small metric allen-wrench set, a small flat-head screwdriver, and a normal pair of pliers to remove the large nuts under the tone/volume/blend knobs.
The grub screw he states is the tiny hex-key screw on each knob.
I think the pickups can come out after being unscrewed with a "Phillips-screwdriver" (obviously, not a mix of Vodka and Milk-of-Magnesia) har har
yeah, sorry about the crud in the Wal. I think this is also part of the cost of ownership. That's why I'm trying to get savvy and know as much as I can about their electronics. I'd like to become a U.S. based tech, if it would save Paul the extra work and shipping.
